When patch 3.3 hits, running instances will be a whole lot easier. The new dungeon tool will make it very easy to find groups. Once I have a few iLevel 200 pieces of gear, I will run random heroics as often as I possibly can for Emblems of Triumph, to trade in for iLevel 245 gear (and 2x Emblems of Frost per day, to be traded in for Tier 10!).
